Site Reliability Engineer (Data Platforms)

Job Description

Posted 8 months ago

The Wikimedia Foundation is hiring two Site Reliability Engineers to support and maintain (1) the data and statistics infrastructure that powers a big part of decision making in the Foundation and in the Wiki community, and (2) the search infrastructure that underpins all search on Wikipedia and its sister projects. This includes everything from eliminating boring things from your daily workflow by automating them, to upgrading a multi-petabyte Hadoop or multi-terabyte Search cluster to the next upstream version without impacting uptime and users.

We're looking for an experienced candidate who's excited about working with big data systems. Ideally you will already have some experience working with software like Hadoop, Kafka, ElasticSearch, Spark and other members of the distributed computing world. Since you'll be joining an existing team of SREs you'll have plenty of space and opportunities to get familiar with our tech ( Analytics , Search , WDQS ), so there's no need to immediately have the answer to every question.

We are a full-time distributed team with no one working out of the actual Wikimedia office, so we are all together in the same remote boat. Part of the team is in Europe and part in the United States. We see each other in person two or three times a year, either during one of our off-sites (most recently in Europe), the Wikimedia All Hands (once a year), or Wikimania , the annual international conference for the Wiki community.

Here are some examples of projects we've been tackling lately that you might be involved with:

  • Integrating an open-source GPU software platform like AMD ROCm in Hadoop and in the Tensorflow-related ecosystem

  • Improving the security of our data by adding Kerberos authentication to the analytics Hadoop cluster and its satellite systems

  • Scaling the Wikidata query service, a semantic query endpoint for graph databases

  • Building the Foundation's new event data platform infrastructure

  • Implementing alarms that alert the team of possible data loss or data corruption

  • Building a new and improved Jupyter notebooks ecosystem for the Foundation and the community to use

  • Building and deploying services in Kubernetes with Helm
  • Upgrading the cluster to Hadoop 3
  • Replacing Oozie by Airflow as a workflow scheduler

    And these are our more formal requirements:

    • Couple years experience in an SRE/Operations/DevOps role as part of a team
    • Experience in supporting complex web applications running highly available and high traffic infrastructure based on Linux
    • Comfortable with configuration management and orchestration tools (Puppet, Ansible, Chef, SaltStack, etc.), and modern observability      infrastructure (monitoring, metrics and logging)
    • An appetite for the automation and streamlining of tasks
    • Willingness to work with JVM-based systems  
    • Comfortable with shell and scripting languages used in an SRE/Operations engineering context (e.g. Python, Go, Bash, Ruby, etc.)
    • Good understanding of Linux/Unix fundamentals and debugging skills
    • Strong English language skills and ability to work independently, as an effective part of a globally distributed team
    • B.S. or M.S. in Computer Science, related field or equivalent in related work experience. Do not feel you need a degree to apply; we value hands-on experience most of all.
